I came across this 1995 mazda millian with 136000 miles.I was told the timing belt had broken and owner chose not to fix it.After I tore it apart, it looked like someone had put new belt on it(it turned over with no compression, like timing issue)I asked the question yesterday about how to check belt tensioner.To make long story short, Im trying to piece together whats wrong.I thought maybe someone put new belt on and didn't load tighner.So I bought new belt, put new crank seal in and went about trying to put the time belt on.(There was evidence of old belt remains which I cleaned up).My book says this is a noninterference engine, but when I turn crank up to notch and pointer it feels like like valves are hitting.Ive tried to turn cam but still feels like it hits.Also I see marks on cam but nothing on engine for marks to time cam.Can you shed some light on this.The more I read the more I'M confused.I've never worked on a mazda before.Thanks

A friend of mine has owned two of these cars he loved them when they were running but when it came time for the timing belt to be changed by the time the cost of the tensioners and water pump and associated timing belt parts were added up I was surprised at how expensive the parts cost. My information doesn't imply the engine is an interference fit engine but calls for t/belt change every 60,000 miles. I don't know what workshop manual you are using, there is a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online

My plan of attack is take spark plugs out and see where pistons are.Can you tell me where the marks are located on heads for cam timing.I haven't taken valve covers off like they said in manual.Is the marks underneath covers?Maybe what I feel when I bring crank to top dead center is compression although it seemed pretty hard.I have bought all the things you mentioned and if I don't have to buy another manual would be nice.If this is not a interference engine and its not compression what could the resistance be.Its within quarter inch from top dead center. Before I tore it apart It spun over with starter with no problem and no compression. Thanks for any help.

According to my info this is a FREEWHEELING engine.
There is a mark on the crank pulley. If you post an e-mail I can send you some info.
